Title: Buffer management method
Inventor: YAMAGUCHI SHOJI
IPC: H04L13/08
Filed: 1988-01-13
Abstract: PURPOSE:To prevent missing of a reception of data by adding a reception processing priority information to a reception data, assigning a buffer in response to the priority and stopping tentatively the reception of the priority reception data when the reception capacity of the reception data with high priority is occupied. CONSTITUTION:When a transmission control section 14 receives a data via a transmission line 16, the data is stored in a PRHB 121 when the priority is placed high and the data is stored in a PRLB 122 when the priority is placed low according to the added priority. When the high priority buffer is occupied, the data reception processing with low priority is stopped tentatively and a free buffer in a free buffer 124 able to be assigned as the low priority buffer is assigned for a high priority buffer and then used. Thus, the reception data missing of the data with high priority due to the busy high priority buffer is prevented and the buffer is efficiently used.

Title: Constant multiplication arithmetic method, and device therefor
Inventor: MATSUURA AKIHIRO
IPC: G06F7/38
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to share plural encoded constants via several constant multiplications and to decrease more number of necessary shifts, additions and subtractions, by calculating the weight to decide the priority of pairs of digits which execute the shifts, additions and subtractions, about a plurality of coded constants. SOLUTION: Plural constants are inputted (S1) and encoded (S2). The weight is calculated (S3) to decide the priority of digits which execute the shifts, additions and subtractions for plural encoded constants. The calculated weight is evaluated, and the operation that should be processed with the highest priority is decided with the operands of the necessary shifts, additions or subtractions (S4). These decided operation and operands are outputted (S5). The partial arithmetic results of shifts, additions and subtractions are effectively shared as the priority that is used for minimization of the final operands. Thus, the number of operands can be decreased.

Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent a complicate structure of a mold for molding by providing a small-diameter part at least at one position of a waste boss in a lengthwise direction. SOLUTION: The molding 1 comprises a slender thin platelike body 2, and a waste boss 3 stood on a rear surface of the body 1.

Title: Idling compensator for electric motor vehicle
Inventor: TAKE TATSUO
IPC: B60L3/10
Filed: 1978-01-19
Abstract: PURPOSE: To shorten the reset time of a drive motor for an electric motor vehicle to its adhesion by flowing larger current through the motor only for predetermined time from idling occurrence time by increasing the difference between the counter electromotive force and the supply voltage at re-adhesion time to thereby increase the torque of the motor at an earlier time.  
     CONSTITUTION: When an idling detector 1 produces an idling detection signal Sp, a compensation signal generator 2 will reduce the current in a drive motor 5 for an electric motor vehicle due to occurrence of the idling at the motor 5 to produce a compensation signal Sc only for predetermined time t from elapse of time T delayed as predetermined to meet the time to reach re-adhesion. This signal Sc turns a switch 3 ON to short part of a main resistor 4 so as to thereby raise the supply voltage E of the motor 5. This increases the difference between the counter electromotive force e and the supply voltage E to thereby increase the current Im in the motor 5 and to accordingly raise the torque of the motor 5 so as to compensate the torque reduced due to the idling of the motor 5.

Abstract: PURPOSE: To provide a flash memory device causing no lowering in an access speed of address retrieval and no revision of software when the data are rewritten from a self system flash memory to another system flash memory by writing in the same address space. CONSTITUTION: When a defect occurs in a sector 00 of a zero system flash memory 1, a self system flash memory storage part 31 sends a self system flash memory communication signal 34 to an access flash memory switch control part 33. The self flash memory in the sector 00 informs that the zero system flash memory 1 is switched to a one system flash memory 2. The receiving switch control part 33 writes the data of the sector 00 of the zero system flash memory 1 in the sector 00 of the one system flash memory 2 to cause it to retreat. In such a manner, by selecting and switching the self system flash memory accessing at every erase unit, only the sector rewriting the data is rewritten to another system memory, and no rewrite speed is lowered.
